“What is particularly striking is that it is erectile,” said
Paul Oliver, a herpetologist at the Queensland Museum and Griffith University
in Australia for National Geographic.
“At times it sticks out quite straight, while at other times it droops
downward. So, they are pretty elaborate structures that must have some
purpose.”

Oliver suspects that such a unique nose could be the frog’s way to identify the species among 450 other frog species that live in the forests. “But the truth is, like so much in biology, we don’t really know,” he said.
